FLEXIBLE JAR CAP GRIPPING WRENCH Filed Oct. 2, 1961 INVENTOR.

MICHAEL L/PSK/ A T TORNE V dtts 2 Claims. 01. s1 3.43)

This application is a substitute application for my application filed May 2, 1946, Serial No. 666,747, now abandoned.

This invention relates to an improved jar cap attaching and removing tool, and one of its objects is to provide a device with a flexible metal band adapted to encircle a jar cap, and means for closing the band about the jar cap in pressure clamping engagement, so as to attach the jar cap to a glass jar or to remove the cap when so attached.

Another object of the invention is the provision of a tool of this type with a metal band having extruded projections formed with holes providing gripping teeth, and a plier-like tool having jaws provided with pins adapted to be inserted in certain of the holes, so that the loop formed by the bending of the metal band may be increased or decreased.

With the above and other objects in view, the invention comprises certain new and useful constructions, combinations and arrangements of parts, clearly described in the following specification, and fully illustrated in the drawings, in which:

FIGURE 1 is a side elevation.

FIGURE 2 is an edge view.

FIGURE 3 is a transverse sectional view, taken on line 33 of FIGURE 1, looking in the direction of the arrows.

FIGURE 4 is a detail sectional view taken on line 4-4 of FIGURE 1, looking in the direction of the handles.

FIGURE 5 is a transverse sectional view, taken through the pivot connection between the companion lever members of the tool. 7

Referring to the accompanying drawings, which illustrate the invention, 5 designates one lever member and 6 the companion lever member of a plier-like tool. The lever member 5 is formed with an offset jaw 7, having a flat side face 7a and a right angular flange 7b. The lever member 6 is formed with an oifset jaw '8, having a flat side face 80 and a right angular flange 8b. The two flat side faces 7a and 8a are pivotally connected to each other by means of the rivet or pin 9.

The lever member 5 is also provided with a handle 10, which is formed tubular, and the lever member 6 is formed with a handle 11, which is formed tubular.

The jaw flange 7b carries a stud pin 12, which projects inwardly, and the jaw flange 8b carries a stud pin 13 which projects inwardly. A flexible metal band 14 is looped or bent upon itself to provide the U- shaped cap gripping loop 15, and the sides of this band are inserted in the hollow or tubular handles.

The flexible metal band is formed with extruded projections 16, which are pierced to provide holes 16a which are sized to receive the pins 12 and 13, and all of these extruded projections face inwardly.

The metal band is adjusted on the pins to provide a loop atent 3,084,573 Patented Apr. 9, 1963 'cap, when it may be screwed on the jar or removed if already on.

The band insures that concentric pressure is applied on the cap, so that if any portion of the cap is distorted it will be forced into a concentric shape, and if the cap is already in a true circular condition it will not be distorted to a non-circular condition by the pressure of the metal band, as it is constricted about the cap by the hand pressure applied on the lever handles.

The extruded projections act as gripping teeth to effectively clutch the rim of the jar cap when they are engaged with the same, so that the metal band will not slip on the cap, when the lever handles are closed upon each other.

Having described the invention, it is understood that various changes in the details of construction, their combination and arrangement, may be made, within the scope of the claims herein set forth, which define the invention.

1 claim as new and patentable:

1. A jar cap attaching and removing tool, comprising a pair of lever members pivotally connected to each other to provide opposing handles at one end of the tool and opposing jaws at the other end of the tool, a flexible metal band looped upon itself and having its sides disposed against the jaws and the handles, said'metal band having extruded projections formed with holes and providing jar cap gripping teeth, and a pin secured to the inner side of each jaw and adapted to engage one of said holes, whereby the loop of the metal band may be increased and decreased, the loop being constricted upon a jar cap when the handles are forced toward each other.

2. A jar cap attaching and removing tool, comprising a pair of lever members pivotally connected to each other to provide a short jaw and a long handle on each member, each handle being tubular and each jaw having a flat side and a right angular flange, a stud pin secured to each flange, and a flexible metal band formed into a loop and disposed between the jaws and having its end portions inserted in the tubular handles, said metal band having extruded projections forming jar cap gripping teeth projecting inwardly from the band and provided with holes and capable of adjustment by said holes with said pins so that the capacity of the loop may be increased or decreased.
